The Wendie plan is just simple calorie cycling. You don't really need a "set up plan" to do this. If your range is 1200-1500 calories, and some days you eat closer to 1200...and other days closer to 1500, then you are pretty much already doing the basic premise of it.
It is essentially basically just eating a slightly different level of calories (or WW points) per day, rather than the exact same number.
